Call it doomsday prepper economics. For more than five years, many Republicans and conservatives have warned that catastrophe is nigh. Washington's deficit spending and the Federal Reserve's excessive money printing will lead to a financial crisis worse than the Great Recession, they prophesied. Inflation will skyrocket, the dollar will collapse, and the Chinese will dump treasuries, they swore. As Ron Paul, the libertarian former GOP congressman and presidential candidate, said back in 2009: "More inflation is absolutely the wrong way to go. We're taking a recession and trying to turn it into a depression. We're going to see a real calamity."

Many GOP politicians have since echoed Paul's prediction. But the Next Great Inflation never happened. The Consumer Price Index, including food and energy, has risen by an annual average of just 1.6 percent since 2008, below the Fed's 2 percent inflation target. During the Great Inflation of the 1970s and early 1980s, by contrast, prices rose five times faster.

This information isn't a secret. The Labor Department releases inflation data monthly on its website. Yet inflation fears still rage on the right. Those concerns are a big reason why Republicans continue to push for a balanced budget ASAP. They're why the GOP wants to saddle the Fed with restrictive new rules.

Regardless of the potential merits of those policy ideas, the inflation alarmism driving them is taking a weird turn. Some Republicans and conservatives now argue that Washington is figuring inflation all wrong, maybe even intentionally. Better, they say, to trust independent outside sources such as the website ShadowStats, which "exposes and analyzes flaws" in government economic data. According to one set of ShadowStats calculations, the true inflation rate is nearly 10 percent today. The inflation truth is out there.

In a recent National Review Online article, conservative author Amity Shlaes approvingly cites ShadowStats as supporting her thesis that "inflation is higher than what the official data suggest." Others fans include conservative intellectual Niall Ferguson, Sen. Tom Coburn (R-Okla.), and a good chunk of the conservative blogosphere.

ShadowStats' popularity on the right is crazy — because the site's methodology has been roundly ridiculed by both economists and business journalists. Critics also note that the subscription price for the ShadowStats newsletter has remained unchanged for years. Inflation for thee, but not for me. Beyond that, MIT's Billion Price Project, which tracks prices from online retailers every day, puts U.S. inflation at just over 2 percent. And consider this: If inflation were really 10 percent, that would mean the real economy, adjusted for inflation, has been sharply shrinking — yet somehow still adding 2 million net new jobs a year.

If GOP inflationistas had their way, the weak U.S. recovery would almost surely be even weaker. Just look at Europe. Unlike the Fed, the inflation-phobic European Central Bank sat on its hands despite weak growth. The result has been an unemployment rate nearly twice America's and a nasty double-dip recession. Of course, inflation is lower than in America — so low, in fact, that the region risks a dangerous deflationary spiral of falling prices and falling wages.

Why this GOP inflation obsession? Maybe it's a legacy of how rapidly rising prices in the 1970s swept conservatives into power in both America and Great Britain. Maybe it's how many conservative talk radio shows are sponsored by gold companies who stand to benefit from inflation hysteria. Maybe it's a belief that every single economic metric must be a nightmare under President Obama.

But whatever the reason, the GOP's preoccupation with phantom price increases is distracting it from the actual problems afflicting the U.S. economy — such as low social mobility, stagnant wages, and the decline of middle-class work. The price of not addressing those issues is rising every year. And that is the kind of inflation worth obsessing over.
